The Prometheus server will not automatically scrape your custom metrics unless you configure it to do so. Here's what you need to do:

Install and configure prometheus for monitoring:

1. Add prometheus helm repo

helm repo add prometheus-community https://prometheus-community.github.io/helm-charts

2. Fetch prometheus values File

helm inspect values prometheus-community/kube-prometheus-stack > /tmp/kube-prometheus-stack.values

3. Add Scrape Configurations in Prometheus Configuration File

## The scrape configuration example below will find master nodes, provided they have the name .*mst.*, relabel the
## port to 2379 and allow etcd scraping provided it is running on all Kubernetes master nodes
##
additionalScrapeConfigs:
  - job_name: 'demo-app'
    scrape_interval: 15s
    metrics_path: /metrics
    static_configs:
      - targets: [demo-app-metrics-service.golang-system.svc.cluster.local:8080]

4. Deploy prometheus in the monitoring namespace

helm upgrade -i prometheus prometheus-community/kube-prometheus-stack -f kube-prometheus-stack.values --namespace monitoring --debug
